HGH Fragment 176-191 5mg

Description

What is HGH Fragment 176-191?

HGH Fragment 176-191 is a synthetic peptide corresponding to amino acids 176 to 191 of the C-terminal region of human growth hormone (hGH). This short 16-residue fragment lacks the growth-promoting activity of full-length hGH but has been reported in preclinical research to retain the lipolytic (fat-mobilising) activity associated with the parent molecule, without affecting IGF-1, insulin sensitivity, or blood glucose in animal models.

It is supplied by Revial Labs as a lyophilised (freeze-dried) powder for reconstitution in bacteriostatic water. All product is intended strictly for laboratory research use.

Areas of Research Investigation

Published research on HGH Fragment 176-191 has been conducted primarily in animal and in vitro models. Areas of research investigation include:

• Lipolysis studies — investigation of fat-cell lipolysis in adipose tissue models.
• β3-adrenergic receptor research — studies of interaction with β3-adrenergic pathways in adipose tissue.
• Body composition models — preclinical studies of adipose tissue mass in rodent models of obesity.
• Structure-activity relationship research — comparative studies of the fragment versus full-length hGH to isolate lipolytic activity.

This is a summary of published research directions and should not be interpreted as claims about the compound’s effects in humans. HGH Fragment 176-191 is not approved by the MHRA, FDA, or any equivalent regulatory body for human or veterinary use.

Frequently Asked Questions

What is included with this product?

One sealed vial containing 5mg of lyophilised HGH Fragment 176-191 powder. Bacteriostatic water, syringes, and alcohol swabs are sold separately — see our Starter Accessory Pack for a bundled option.

How pure is Revial Labs HGH Fragment 176-191?

All HGH Fragment 176-191 supplied by Revial Labs is manufactured to ≥99% purity and independently verified by High-Performance Liquid Chromatography (HPLC). A batch-specific Certificate of Analysis is available on request.

How does HGH Fragment differ from full-length hGH?

In preclinical research, HGH Fragment 176-191 has been reported to retain the lipolytic activity of the C-terminal region of hGH while lacking the anabolic and IGF-1-stimulating effects of the full protein. This selectivity has made it an area of interest in metabolic research where investigators want to study adipose-tissue effects without confounding growth-axis activation.

How is HGH Fragment 176-191 shipped?

Orders are dispatched via Royal Mail tracked delivery from the UK, typically within one working day. Peptides remain stable at ambient temperature during transit; refrigeration is recommended once received.

Is a Certificate of Analysis included?

A batch-specific COA verifying identity, purity, and mass spectrometry is available on request. Contact us with your order number and we will send the corresponding document.
